一台 PC 的好坏取决于其各部分的总和，其中包括用于控制其许多组件的软件。该软件称为驱动程序——它们允许 Windows 通信和控制 PC 的不同部分，将指令转换为硬件本身可以理解的合适代码。
这些驱动程序会偶尔进行错误修复和功能升级，从而提高Windows PC 的整体稳定性。不幸的是，就像任何人造代码一样，驱动程序更新可能与它们替换的驱动程序一样有问题。如果更新导致您出现问题，您需要知道如何在Windows 10中回滚驱动程序。
为什么要在 Windows 10 中回滚驱动程序？(Why Should You Roll Back a Driver in Windows 10?)
新的(New)驱动程序更新非常普遍，尤其是对于显卡等设备。这些通常带有新功能和修复程序，可以提高 PC 的整体稳定性并提高它们控制的设备的可用性。
不幸的是，这并不意味着您安装的所有驱动程序都是稳定的。例如，如果您是使用NVIDIA显卡的游戏玩家，您可能首先将您的 NVIDIA 显卡驱动程序(ics drivers)更新(updating your NVIDIA graph)为未经测试的 beta 测试驱动程序，从而为最近发布的下一代游戏提供支持。
该驱动程序可能会为该游戏带来支持，但它可能会带来其他问题，这些问题只能通过进一步、更广泛的测试来解决。不过，这并不意味着稳定的驱动程序会更好——它们也可能带有开发人员在驱动程序发布之前无法找到或修复的问题或错误。
如果发生这种情况，并且您的 PC 仍然足够稳定以启动，您可以将驱动程序回滚到以前安装的（希望更稳定）驱动程序版本。
如何备份 Windows 10 驱动程序(How to Back Up Windows 10 Drivers)
你应该确保你有一个系统来备份你的驱动程序。如果您需要将设备驱动程序回滚到早期版本，这将有助于您，因为您将拥有旧设备驱动程序的副本。
Windows通常不会删除旧驱动程序，即使您回滚到旧版本也是如此。但是，备份Windows 10 驱动程序可以帮助您快速恢复这些驱动程序，以防您日后被迫擦除并重新安装 Windows 。(wipe and reinstall Windows)
如果发生这种情况，如果您打算恢复使用较旧的驱动程序，而不是使用有问题的较新驱动程序版本，您将需要这些较旧的驱动程序。幸运的是，您可以使用部署映像服务和管理 (DISM)(Deployment Image Servicing and Management (DISM) )工具创建已安装设备驱动程序的快速备份。
- 要使用DISM工具备份驱动程序，您需要使用管理权限打开一个Windows PowerShell窗口。(Windows PowerShell)为此，请右键单击Windows 开始(Windows Start)菜单并按Windows PowerShell (Admin)选项。
- 在 PowerShell 窗口中，键入DISM /online /export-driver /destination:C:\Drivers，将C:\Drivers 文件夹替换为驱动程序备份的另一个合适位置。这会将所有可用的第三方驱动程序复制到此文件夹，以便您稍后恢复它们。
- 但是，如果您想备份全套可用的Windows驱动程序，则需要手动执行此操作。Windows 10 将驱动程序存储在C:\Windows\System32\DriverStore\ 文件夹中。要备份此文件夹，请打开Windows 文件资源管理器(Windows File Explorer)并访问C:\Windows\System32 文件夹。
- 右键单击DriverStore文件夹并点击复制(Copy)选项，或选择它并按键盘上的 Ctrl + C
- 复制DriverStore(DriverStore)文件夹后，将内容粘贴到合适的备份文件夹中（例如C:\Drivers）。这将允许您之后手动恢复它们。
- 如果您以后需要重新安装这些驱动程序，您可以使用PnPUtil(PnPUtil )工具一次性安装它们。在具有管理权限的PowerShell窗口中，键入(PowerShell)PnPutil /add-driver “C:\Drivers\*.inf” /subdirs /install /reboot。这将安装此文件夹中的所有驱动程序，重新启动您的 PC 以完成该过程。
如何在 Windows 10 中回滚驱动程序(How to Roll Back a Driver in Windows 10)
如果您需要在Windows 10(Windows 10)中回滚驱动程序，您可以使用Windows 设备管理器(Windows Device Manager)执行此操作。设备管理器(Device Manager)列出所有检测到的设备和连接的硬件，允许您为每个设备安装、升级或回滚驱动程序。

虽然您可能需要不时回滚驱动程序，但不要害怕检查定期驱动程序更新(check for regular driver updates)并将它们更新到最新版本。驱动程序(Driver)问题应该不常见，新驱动程序应该会提高您 PC 的整体稳定性。毕竟，如果出现问题，您始终可以回滚驱动程序。
How To Roll Back A Driver In Windows 10
A PC iѕ only аs good as the sum of its parts, and that includes the software used to control its many сomponents. This software is called drivers—they allow Windows to communicate and contrоl diffеrent parts of your PС, convеrting instructions into suitable code that the hardware can itѕеlf understand.
These drivers are subject to occasional bug fixes and feature upgrades that can improve the overall stability of your Windows PC. Unfortunately, like any man-made code, driver updates can be as problematic as the drivers they replace. You’ll need to know how to roll back a driver in Windows 10 if an update causes you issues.
Why Should You Roll Back a Driver in Windows 10?
New driver updates are quite common, especially for devices like graphics cards. These often come with new features and fixes which can improve the overall stability of your PC and improve the usability of the devices they control.
Unfortunately, this doesn’t mean all drivers you install are stable. For instance, if you were a gamer with an NVIDIA graphics card, you might start by updating your NVIDIA graphics drivers to an untested driver in beta testing, providing support for a recently released, next-generation game.
This driver may bring support for that game, but it may come with additional problems that can only be resolved with further, wider testing. That doesn’t mean stable drivers are any better, though—they can also come with issues or bugs that the developer wasn’t able to locate or fix before the driver was released.
If this happens, and your PC is still stable enough to boot up, you can roll back a driver to the previously installed (and hopefully more stable) driver release.
How to Back Up Windows 10 Drivers
You should ensure that you have a system in place to back up your drivers. This will help you should you need to roll back a device driver to an earlier version, as you’ll have a copy of your older device drivers available.
Windows won’t typically delete old drivers, even when you roll back to an older version. Backing up your Windows 10 drivers can help you quickly restore these drivers should you be forced to wipe and reinstall Windows at a later date, however.
If that happens, you’ll need these older drivers to hand if you intend to revert to using an older driver, rather than a problematic newer driver release. Thankfully, you can create a quick backup of your installed device drivers using the Deployment Image Servicing and Management (DISM) tool.
- To use the DISM tool to back up your drivers, you’ll need to open a Windows PowerShell window with administrative privileges. To do this, right-click the Windows Start menu and press the Windows PowerShell (Admin) option.
- In the PowerShell window, type DISM /online /export-driver /destination:C:\Drivers, replacing the C:\Drivers folder with another suitable location for your driver backups. This will copy all available third-party drivers to this folder, allowing you to restore them later.
- If you want to back up the full set of available Windows drivers, however, you’ll need to do this manually. Windows 10 stores drivers in the C:\Windows\System32\DriverStore\ folder. To back up this folder, open Windows File Explorer and visit the C:\Windows\System32 folder.
- Right-click the DriverStore folder and hit the Copy option, or select it and press Ctrl + C on your keyboard.
- With the DriverStore folder copied, paste the contents into your suitable backup folder (for instance, C:\Drivers). This will allow you to restore them manually afterward.
- If you need to reinstall these drivers in the future, you can install them all at once using the PnPUtil tool. In a PowerShell window with administrative privileges, type PnPutil /add-driver “C:\Drivers\*.inf” /subdirs /install /reboot. This will install all of the drivers in this folder, rebooting your PC to complete the process.
How to Roll Back a Driver in Windows 10
If you need to roll back a driver in Windows 10, you can do this using the Windows Device Manager. The Device Manager lists all detected devices and attached hardware, allowing you to install, upgrade or roll back drivers for each device.
- To access the Device Manager, right-click the Windows Start menu and press the Device Manager option.
- The Device Manager menu separates all attached hardware into categories. Press the arrow next to any of these categories to view a full list of hardware.
- To roll back a driver, right-click any of the listed devices and press the Properties option.
- In the Driver tab of the Properties window, press the Roll Back Driver option. This will allow you to begin rolling back your installed driver to a previous version.
- Windows will ask you to confirm why you’re rolling back your driver. Select a reason from one of the selected options—feel free to add an additional comment in the Tell us more box. When you’re ready, press the Yes button.
Once you confirm why you’re rolling back the driver, Windows will automatically begin the process. You may need to restart your PC once this process has completed to fully reload the old driver and ensure your PC is working correctly.
- Should you wish to return to the newer driver at a later date, return to the Device Manager window, right-click a driver and press Properties. In the Driver tab of the Properties window, press the Update Driver button.
- In the Update Drivers window, press the Search automatically for updated driver software. This will search your PC and Windows Update for the newer driver. If your rolled-back driver is older than the most recently released driver, this should update your driver to the newer version.
- Windows will confirm when the new driver has been installed—press Close to confirm and close the Update Drivers window.
Effective System Maintenance in Windows 10
Knowing how to roll back a driver in Windows 10 is just one necessary step in ensuring you know how to stay on top of the system maintenance of a Windows 10 PC. You could take things further by setting up automatic Windows backups, giving you the option to restore your PC if something goes wrong in the future.
While you may need to roll back drivers from time to time, don’t be afraid to check for regular driver updates and update them to the latest versions, too. Driver problems should be uncommon, and new drivers should come with improved stability for your PC overall. After all, if things go wrong, you can always roll back your driver.
